Part Number: TPS54527 Other Parts Discussed in Thread: TPS54327 Hi
My Customer has question.
When the customer check the rising waveform, customer found an interesting point. Currently this waveform is not a problem, Will not you get advice on whether this…
Part Number: TPS54327 Other Parts Discussed in Thread: TPS54527 Hi Team,
my customer uses the TPS54327 and TPS54527 to generate the 3.3V rail in the system. In the manufacturing process he will power the 3.3V rail from an external source to program the microcontroller…
Part Number: TPS54327 Hi Team,
One of our customers has asked whether the TPS54327 has reverse current protection.
His application has 3 separate sources for 3.3V, which are never on at the same time, however he is worried about backfeeding the TPS54327…
Part Number: TPS54327 Hi all Would you mind if we ask TPS54327? Please refer to the attachment file.(Vin=12V, Vout=1.5V) 20170418_TPS54327.pdf Our customer changes the inductor value from 1.5uH to 2.2uH. In this condtion, when the load changes from 1A to 2A…
Part Number: TPS54327 Hi Support,
The datasheet states that output capacitance should be between 22-68uF. Am using 220uF caps (Chemi Con part EMVA100ADA221MF80G). Is there any concern? In addition, could you advise the limit on the output cap?
Thanks.

Hi Ikon,
1. Phase Margin & Soft Start Delay
- How to check and what is deemed as correct value?
For phase margin, connect a frequency response analyzer in your FB loop. Phase margin should be higher than 45deg. For the soft start, just monitor…
Part Number: TPS54327
Hi all Would you mind if we ask TPS54327? Is it possible to set soft start time over 8ms? (Does upto 8ms mean avilable linear setting area?) Because, we could not configure over 8ms on the Webench simulation. Our customer would like to…

Other Parts Discussed in Thread: TPS54527 , TPS54327 Hi
My customer uses TPS54527.
When they let it short-circuit between VIN and VBST terminal,
this devise emitted smoke.
As long as I read the datasheets of TPS54327 and TPS54527,
these devise are same…
